If your internal memory drops below 10MB or 12MB the BlackBerry might be clearing chats to free up this memory. It's needed for the OS to run properly. Text messages, calendar events, chats, and even email messages can be lost to critically low internal memory.
Yeah its def on the mem card. I went thru the contents of the mem card thru my computer and the chats with the contacts that I have noticed to go missing, are all the same size. 147kb "OLD" files. This problem isn't that big a deal but it is sorta disappointing.
